Ballast Resistor Not Resisting Electrical The Classic

This simple system is easy for even the novice mechanic to wire.

Ballast resistor needed. Some are designed for a ballast resistor and others do not require one. Once the starter is disengaged the bypass shuts off and the coil gets its 12 volt source thru the ballast which drops it down to the 6 8 volt range if i understand what i have read about ignition circuits. The job of the ballast resistor was to inhibit current to a level that would not overheat the coil.

The ballast resistor is commonly found in older vehicles because they did not have the benefit of circuit boards found in most of todays vehicles. In simple terms the ballast resistor in a mopar limits the amperage or current flow through the coil while the engine is running thereby extending the life of the coil and breaker points of the. So if you have a classic car with missing ignition components dont hesitate to replace the coil and ballast resistor yourself.

Additional uses low voltage lighting systems such as florescent led and neon lights frequently contain ballast resistors. Need to report the video. The ballast resistor then functions to regulate the voltage going to the ignition system to avoid additional wear on the system.

On a car which uses a br often the starting circuit bypasses it to allow a hotter spark for starting. This video explains how the ballast resistor works.
